The utility model relates to a disc edge scraping device for a pellet pelletizing disc, and belongs to the technical field of pellet production in the metallurgical industry. According to the technical scheme, according to the material scraping sequence, an inclined material scraping plate (10) and a straight material scraping plate (11) are sequentially arranged on the edge of a pelletizing disc (3), a certain included angle is formed between the inclined material scraping plate (10) and the pelletizing disc (3), the straight material scraping plate (11) is perpendicular to the pelletizing disc (3), the inclined material scraping plate (10) is connected to the lower end of an inclined material scraping plate pull rod (9) through a rib plate, and the inclined material scraping plate pull rod (9) is connected with the straight material scraping plate (11). The upper end of the inclined scraping plate pull rod (9) is rotationally connected to the suspension frame (5) through a rotating shaft (7), the straight scraping plate (11) is connected to the lower end of the straight scraping plate pull rod (8) through a rib plate, and the upper end of the straight scraping plate pull rod (8) is connected to the suspension frame (5). The device has the advantages that accumulated materials on the edge of the pelletizing disc can be cleaned in real time, and materials and green pellets moving upwards along with the pelletizing disc are effectively blocked.

This application provides a molten steel slag mixing, solidification, and crushing system and method. The system includes a processing chamber, a mixing zone, a slag dumping device, a feeding device, a stirring and crushing device, a screening device, and a dust removal device. The slag dumping device and the mixing zone are located in the processing chamber. The slag dumping device is used to dump molten steel slag into the mixing zone. The feeding device is used to send solid cooling medium into the mixing zone. The stirring and crushing device is located in the mixing zone and is used to stir and mix the molten steel slag with the solid cooling medium, so that the molten steel slag cools, solidifies, and is crushed into granules. The screening device is located on one side of the mixing zone and is used to separate and output the crushed and granulated steel slag according to particle size. The dust removal device is connected to the processing chamber. This application achieves efficient cooling and crushing by mixing solid cooling medium with molten steel slag, integrates a screening device to simplify the process flow, and adopts closed treatment and dust removal to improve environmental performance. It has the advantages of high waste heat recovery efficiency, high processing efficiency, low investment cost, and good environmental performance.
